LlNOTY PE-MACHINE.

SPECIFICATION forming part of LettersPatent N 0. 652,855, dated July 3,1900.

Application filed April 7, 1900.

To aZZ whom it may concern:

Be it known that I, CARL MUnHLEIsEN, of Baltimore, in the State ofMaryland,- have invented a new and useful Improvement inLinotype-Machines, of which the following is a specification. I I

The presentinvention has reference to linotype-niachines in whichmatrices containing the type characters are stored in a magazine, fromwhich they are delivered one at a time in the order in which theircharacters are to appear in print and to which they are returned afterbeing usedby a distributing mechanism.

The object of the invention is to permit the speedy change from matricesrepresenting characters of one style or size to another set or fontcontaining characters of a difierent style or size; and to this end itconsists in the combination of two independent magazines mounted in suchmanner that they may be instantly reversed, or, in other words, invertedor turned over, in order to permit one or the other to be brought intoaction and in operative relation to the assembling and dis-. tributingmechanisms. I While the invention is applicable in general to machinesusing matrices or type, I have illustrated in the accompanying drawingsdetails of construction more particularly adapted for use in theMergenthaler linotypemachine of the present day-such as is rep resented,for example, in Letters Patent No. 557,000, dated March 24, 1896. Withthe exception of the magazines and their adjuncts the machine may be inall particulars of ordinary construction.

Figure l is a front elevation of the machine provided with myimprovement; Fig. 2', a side elevation of the upper portion of themachine with the parts in operative position; Fig. 3, a similarelevation with portionsin vertical section, showing an intermediateposition of the parts'during the reversal of the magazine. Fig. 4 is asimilar view showing the parts at a more advanced stage in the reversal.Fig. 5 is a front elevation of themagazines and their supports in thepositionshown in Fig. 3. V

Referring to the drawings, A represents the main frame, and B and B theinclined magazines in which the matrices'are stored, only Serial No.12,005. (No model.)

one magazine being in operative position at a time.

0 is a series of vertical rods controlled by finger-keys D and servingto cause the action of the escapement devices in'the lower end of themagazine to deliver the selected matrices one at a time from the lowerend of the magazine through the vertical guides or channels G to theinclined assembling-belt H, over which the matrices descend one at atime into the assembling-elevator I, where they are composedin line.When the composition of the line is completed, the elevator I is lifted,carrying the matrices between two fin gers L on a horizontal carriage,by which the line is transferred through the intermediate guide orchannel M into the first elevator N, by which the matrices are firstlowered to the slotted mold in the wheel 0 and thereafter elevatedabovethe original level to a horizontal shifter S, by which the line ispushed out of the elevator N to the right and into engagement with thebart on the second elevator-arm T, by which the line is lifted to thefeed-box X of the horizontal distributer at matrices to traverse thisbar until they reachpoints over the appropriate magazine-channels, whenthey are released and permitted to fall into the magazine. I

The foregoing parts and the mechanism for supplying the molten metal tothe mold may all be constructed in accordance with Patent No. 557,000and the basic Patent, No. 436,532.

In the ordinary machine there is employed a single magazine B, which isfixed in position when the machine is in operation and removed whollyfrom the machine and replaced by another magazine containing a differentfont of matrices when speedy change from one style of type to another isrequired. I now employ two magazines B and B as permanent members of themachine. 'As shown herein, each magazine is of the ordinaryconstruction, comprising parallel top and bottom plates fixed at asuitable distance apart to admit the matrices between them and groovedlongitudinally in their proximate faces to'receive and guide the ears ofthe matrices. At the upper end each magazine is provided with the usualgrooved throat or entrance I) to receive the matrices from the overlyingdistributer and direct them downward into the magazine-channels. At thelower end each magazine is provided with the usual vibrating escapementb for each channel to effect the release of the matrices one at a time.The matrices enter the operative magazine, as usual, at the upper endand sliding down are discharged one at a time by the correspondingescapements, that they may pass to the assembling devices. Eachescapement device is notched or shouldered in the rear edge, asheretofore, to engage with the upper hooked end of the operating bar orrod 0, as plainly shown in Fig. 2.

In order that the two magazines may be mounted permanently in themachine without conflicting with the other parts and that they may bebrought alternately into operative position, I mount them,as shown, oneabove the other, with their lower sides or sides which bear theescapements facing each other, or, in other words, so that when onemagazine is right side up the other is wrong side up. Each magazine hasits deliveryend, or end carrying the escapements, arranged adjacent tothe receiving end of the other magazine. They are mounted in andarranged to slide forward and backward through a supporting-frame 1,being separated from each other by two horizontal rollers 2 2, mountedin said frame and held inward against the intermediate rollers byoutside rollers 3 3 or equivalent guides or confining devices carried bythe frame 1, the arrangement being such that'when the magazines are outof connection with the operating devices at the bottom and thedistributer at the top they may slide end wise in a forward-andbackwarddirection, and this in order that the magazine which is for the timebeing lowermost and out of action may be carried clear of contact withother parts in the machine.

The roll 2, by which the magazines are separated, is provided withpinions 5, engaging corresponding teeth on the magazine, so that when acrank is applied and the roller turned one magazine will be shiftedrearward, while the other is shifted forward.

The frame 1, in which the two magazines are directly supported, is inturn supported by a frame 6, lying transversely of the machine andhaving an internal circular opening to receive the frame 1 and admit ofits being revolved in a direct-ion transverse to the front of themachine, so that one magazinc or the other may be brought to the toppreparatory to its being adjusted in operative position. The frame 1 ispreferably provided with sustaining-rollers 7, traveling on the insideof the transverse annular frame 6, in

order to reduce the friction; but it is to be understood that these arenot necessary elements of the construction. The outer sustainingframe (3is provided with and sustained by horizontal trunnions 8, lying parallelwith the front of the machine and sustained in the main frame, thesetrunnions permitting the two frames to be tipped or rocked in aforeand-aft direction, so that the magazines supported therein may betipped from the inclined position,in which they operate, to a horizontalposition, as represented in Figs. 3 and 5.

From the foregoing it will be observed that the magazines are capable ofthree movements-first, a sliding motion, one forward and the otherbackward second, the tipping motion around the journals 8 as a center,so that the magazines may assume a horizontal position, and, third, arotary motion from right to left in order to invert or reverse themagazine.

In action the upper magazine is in use, its upper end or entrance-mouthstanding, as usual, immediately under the distributer X to receive thematrices, while its lower end is in position to deliver into thechannels leading to the assembler and with the escapement devices inengagement with rods C. When the lower magazine is to be brought intooperative position, the rods 0 are disengaged from the escapements, themagazines tipped up to a horizontal position, as shown in Fig. 3, thepinions 5 turned to slide the upper magazine backward and the lowermagazine forward, after which the frame 1 is revolved within frame 6 tocarry the upper magazine down and bring the lower magazine B to the top,after which the magazines are tipped down to the original inclinationand the proper connections made with the upper magazine.

The proper position of the operative magazine may be secured by theusual set-screws 0 under its lower end or otherwise. Locking devices ofany suitable character may be employed to hold the parts in theiroperative positions. For instance, the frame 6 may be held from tippingby means of a locking-pin 10, inserted through the side of the mainframe, or by any equivalent locking device. The rotation of the frame 1within the outer. frame is impossible when the operative magazine restson the supporting-screws-D under- During the reversal of the its lowercorners. magazines the frame 6 may be held in-the required verticalposition by a latch 11 in the main frame-or by other suitable means.

The essence of my invention resides in mounting two magazines inrevoluble supports, so that they may be inverted at will, and it ismanifest that the detailsof construction may be widely modified withoutdeparting-from the limits of my invention.

While the longitudinal sliding motion of the magazines is necessary inthe commercial linotype-machines of the present day in order that theunder magazine may be kept out of contact with the main frame and otherparts, it is obviousthat such sliding motion IIC is unnecessary when theinvention is used in a machine having its frame cut away to give thenecessary clearance when the magazines are reversed.

I believe myself to be the first to provide a linotype or other machinefor composing type matrices or dies with two distinct magazines adaptedfor reversal or inversion, so that either one may be brought intooperative po- IO sition and the other at the same time carried out ofthe way to an inoperative position.

The word inversion appearing in this specification and in the claimsfollowing is used in its ordinary signification-that is to r 5 say, asindicating magazines which are capable of being turned over in orderthat one side or the other may be brought uppermost.

Having described my invention, what I claim is- 1. In a linotype orkindred machine, two magazines mounted for inversion therein.

2. In a linotype-machine, in combination with a distributer and acomposing mechanism, two intermediate parallel magazines,and

supports permitting said magazines to be inverted, whereby one or theother may be brought into operative position.

3. In a linotype-machine, two magazines mounted to slide endwise inrelation to each other, in combination with supports adapted to permitthe magazines to be tipped from an inclined to a horizontal position andalso to permit them to be inverted.

4. In a linotype-machine, the combination of a supporting-frame 6,mounted on hori- 5 zontal axes, a secondary frame 1 revoluble within theframe 6 at right angles to its axes, and two magazines sustained andmovable endwise within the frame 1, substantially as described. 40

5. In a linotype-machine having a distributing mechanism and a composingor assembling mechanism, two flat intermediate reversely-arrangedmagazines, and supports permitting one magazine or the other to bebrought into operative relation to the distributing and composingmechanisms. 1

6. In a linotype-machine, two flat parallel magazines provided withescapement devices on their proximate faces, and revoluble sup- 5oporting devices for said magazines, allowing either magazine to bebrought uppermost at will.

In testimony whereof I hereunto set my hand, this 24th day of February,1900, in the presence of two attesting witnesses.
